To alwhommayc'ofncem:

Berit known that I, C' S. PARKER,

a citizen of the United States, residin at Boston, in the county ofSuffolk and tate n of Massachusetts, have invented certain new anduseful Improvements in Safety Razors, of which the following is aspecification.

This invention relates to improvements in safety razors. Since theadvent of the first razor of this type many e'orts have been made to.improve them, but every type now available, so far as I am aware, isopen to objections in the way of multiplicity of parts and expenseformachine work in its production. the elimination of which is among theobjects of the present invention. And although razors now known aretransformable into a lmocked-down condition, they are still so bulky asto require carriage in a traveling bag and cannot be put into asullicientl small space to satisfy the ideal of one w ose taste ornecessity makes him fastidious in that respect.

It is an object of the invention to meet these means without sacrificeof normal size,

rigidity of blade, or of eiliciency of shaving' qualities. n thecomplete razor of the invention by which these objects are attained, theholder for the blade has only two parts, one of which provides the guardfor the cutting edge, and positions the blade with regard to it, and theother of which coacts therewith to retain the blade rigidly, and servesas the handle. The separate parts may be stamped'from sheet metal in oneoperation, and bent to shape in the second operation; so that, asidefrom finishing l' or plating, no other work is required in theirproduction. The blade may be of any of a number of standard makes andsizes now on the market, or may be specially desigped, with sin le edgeor double edge. The w ole, when taen apart, maybev packed with thehandle, blade and platev in parallelism, substantially within a spacerequired for the lplate and its guard edge alone; so small as to, meanonly -an unappreciable shape and weight in ones waistcoat pocket, or onones ke ring. l

t is mtended that the patent shall cover,

b suitable expression in the ap nded c aims, whatever featuresofpatentablii5 novelty exist in the invention disclosed n the drawings:f AFigure 1 is a ront elevation of one embodiment of the invention;

Figure2 is a side jperspective partly in section, on line 2-2 o Figure1;

Figure 4 is a side elevation of the modiiication seen in Figure 3, withortions shown in section on the line 4-40 Figure 3;

Fi re 5 is a front elevation showing still anot er application of theinvention, this being Yin connection with a blade having two cuttingedges; v

Figure 6 is a side view of the structure of Figure 5, partly in sectionon the line 6 6 .of Figure 5; and

Figure 7 is a plan of'the structure of Figure 5, in section on the line7-7 of Figure 5.

Referring to the ldrawin s, an oblong holder and guard plate 10 1sprovided by stamping from thin sheet metal of suitable quality andthickness, and by the stamping is provided with an elongated opening 12along that which is to beits guard edge.

In Figure 1 the upper corners are shown clipped, but this is a matter oftaste, and the corresponding parts in Figures 3 and 5, are unclipped andin Figure 5 constitute a guard for the second edge of a two-edged blade.l

The lower ed e of the holder plate is turned backwar from the eye, asseen in Figure 1, to form a guard lian e 24 by being bent on lines 13 atthe end o? the opening, and the part of said Harige which constitutesthe ed e of the opening l2 is serrated with guard ngers 16 projectininto the opening. The o posite side 18 o the opening 12 is a straig Vtedge and, in the finished razor, may be beveled on its front as at 19 tormit the blade to operate close to the sur ace that is to be shaved. Theparts 20 of the plate 10 at'the ends of the opening 12 support theilange 24 and are guards which protect the sh'avers face from 'thecorners of the razor 28, which lie back of it as seen .by dotted linesin Figure 1. At the top edge of the plate 10 is a small flange 22, alsobent backward. Lugs 26 may also be turned back in the positions shown inFigure 1 where they engage the side edges of the blade 28 to limit itsslipping down and sidewise on the holder.

The holder constituted by the plate l0 and its turned back'lugs 26 andflange 22 makes a sort of cup into which the blade 28 may be laidwhenpthis is held with the flange 22 and lugs i 26 projecting upwards..In that case Athe flange 22`and ugs 26 position the blade in suchlocation that its cutting' edge 29 runs along the opening 12 and isexposed through it. It is clam ed 1n that po.- sition by the handle 32whic in the shape illustrated in Figures 1 and 2 is made of a piece ofspring bar metallone end of which is bent at 38 into a h ook or loopwhose end 34 and part 36 next back -of` the bend 38 constitute the twospring clamping members which embrace the blade 28 and the holder plate10, pressing them flat together. It 1s applied by sliding it downward,as the parts are represented in Figures 1 and 2, from the top edge intothe position illustrated. To

hold the parts firmly together while the razor is in use, the notch isshaped in the outer edge of the guard flange 24, just wide enough toreceive the barof the handle 32, and the handle itself is bent at suchan angle from the clamping hook- 34, 36, that when the bend 38 of thelatter becomes seated in a notch 14 in the flange 22, against the topedge of the plate 10, the shank of the handle 32 becomes seated in thenotch 40. So long as the handle bar remains thus seated in the ler:

notches 14. 40, it cannot be slipped or twisted sidewise, and thewholeis secure. `Friction tends to hold everything in place because ofthe clamping; and there is no tendency for the clamp to be displacedupward because when in use the handle is pulled only downward; and in sofar as the parts are subject to any upward pressure of the users.beardor face on the guard 24 or on the cutting edge 29 of the blade, thatupward pressure merely tends to seat the two the 'more firmly within theloop, and to seat the back ed of the blade 28 the more firmly against te top flange ofthe holder plate. In thisl po'-l sition the razor isready for use. The remainder of the handle 32 may be made in anysuitable shape, one shape beingillustrated in Figure 2. When thus shaped.it is conveniently and firmly held by the user between his thumb placedonthe side which toward the eye in Figure 2, his second finger on theside which is away from 'the eye, and

his first finger in the hollow 33, or bridging across that hollow fromthe point 35. Totake the instrument apart lone holds the blade 28 andplate 10 between thumb and :torefinger of onehand, and pushes'upwar'd onthe handle with the other hand causiii? the clamping loop 34, 36, 38, toslip oifan so leaving lthe blade 28 free to be lifted or l oblong holel14 into` which' rojects the end Y 46 of a handle 32made o flat barmetal. The end which thus penetrates the hole 14 constitutes the fulcrumof a lever which has a bend of about 45 at 47, where it is ap-V plied tothe flat side of the blade and presses the blade 28 against the plate10. Further swinging of the lever in the same direction gets it toposition where it is latched by engagement with the guard flange24. The

latter has a sub-flange 50 in which is a recess 49, in which recess is atongue 48 that constitutes the latch by springing into an opening 31 inthe flat bar handle 32. This latch is constituted by the spring actionof the guard flange 24 and adjacent parts 20 of the holder plate 10,which permits the,

part V24 to be pressed` downwardto the left as [seen in Figure. 4 farVenough for the -tongue 48 to slip into and out of the hole 31A in thehandle. For assembling, the parts need only to be put togetherandpressed together. For taking apart one presses in the properdirection on the flange 24 in order to draw the tongue 48 out of thehandle.

Figures 5, 6 and 7 illustrate another modi fication. In this case theblade 28 has two cutting edges 29 the one which is not set forl usebeing fully protected by lying against the plate 10 as in the case ofplate 10 shown in the other figures, except that the positionving lugs26 and blade notches 30 are set'sothat its upper edge 29 does not touchthe upper flangeI 22 of the plate 10'. Said upper flange 22 extends forthe full length of the plate 10" thus projecting the entire length ofthe edge of the blade. The pl'ate 10 v might be designed for the blade28 thusy positioned on the plate 10 to be clamped thereon'bya springclamp handle l as shown i'n Figures 1 and 2; but a still differentmethod is illustrated in Figures 5,- 6

and 7 wherein the plate 10 .is represented as `having a formation .42 ofmetal stamped in its midst, constituting a face groove, which v isclearly seen" in Figurel 7 partg34 of the' handle can in'it is held bythe walls of the groove'so that it cannotl twister slip sidewisef? f.

Other variatlons may be made in into which A the slide, andlwherestructingthe razor-.fief the invention.

,afeature that the ty'pe of construction depress together the plate andblade.

plate with ard dan v gu bidi and a bent dat bar handle adapted to enparts re uired are the handle and the. -f' ing hol er. These latter maybeso smallV as to be substantially no. greater in le" -h and breadthover all than the blade itse f; and ample strength is obtained iffv thebar metal emplo ed is only a quarter of an inch broad. As t e guard 24need not be so wide as this, it makes the whole, when the handle isremoved and laid fiat on the bladeand plate 10, occupy a s ace underfive-sixt,- teenths of an inch thic and barely lar er than the blade.When placed in a suite 'le case these parts are an unappreciable burdento one who has occasion to carry them. The manufacture, at the sametime, is so simple f "f that the whole may be inexpensive.
